! 'o alZ whom it may concern:

Be it known that I, AMBRosIUs BRIECHLE, a citizen of the United States, residing in the borough of Brooklyn, city and State of New York, have invented new and useful Improvements in Accounting-Machines, of which the following is a specification.

Modern calculating machines include selective mechanism, as a keyboard, on `which amounts are set up to be accumulated on a series of counters. Printing devices cooperate with a platen mounted on a carriage removably secured to the frame of the machine. to list the amounts set up on the keyboard, on a paper web or Work sheet on the platen. Y

Heretofore, means have been provided to successively feed separate Work pieces, as envelops, for instance, to the printing de vices, and to discharge them from in front of such devices.

(lne object of the present invention is the provision of a simplified and novel means to feed separate Work pieces singly and successively to the printing devices, and to eject the Work pieces from in front of the printing devices, such means being driven from the calculating machine as an incident to the operation of such lnachine in refristering amounts on the accumulatore. The mechanism of the invention is positive in its operation, and comprises but few parts not liable to get out ot' order.

Another object is to positively effect the printing of the amounts. or the location of thc Writing line, on the respective Work pieces, at a predetermined point.

A 'further object is to effect the advance of the Work pieces to the printing devices and their discharge from in front thereof by a single self-contained injector and ejector mechanism.

.i still further object is to positively insure the feed of the envelops singly to the printing devices. Which I accomplish by the provision of a novel feed mechanism adapted to engage beneath the flaps of the individual envclops to Withdraw them one by one from the storage compartment.

The flap of the foremost envelop lifts sufficiently to admit of the insertion of the feed device between the flap and the body of the envelop when the envelop is to be advanced.

In addition, I provide restraining means, the operation of which is synchronized With the operation of the feedin means, to prevent the Withdrawal of adcIitional envelops by reason of frictional contact with the positively fed envelop.

Still another object is to enable the opcrater to list the several amounts on an independent paper, in addition to printing such amounts on the separate Work pieces, from a single set of printing devices, and to this end I have contrived a combined envelop and paper feeding device, whereby the envelope and paper web lie one behind the other relatively to the printing devices, with a transfer medium, as carbon, interposed between the paper and the envelops. The side of the paper web facing the envelops may be coated with carbon to effect the imprint of the amounts on the envelops, or a separate carbon web may be used.

Another object is the provision of compact. and simple means driven from the calculating machine incidentally to the accumulation of items therein. to operate the paper feedingnneang and the ingector and ejector mechanism, as well as the restraining means Which prevents the frictional Withdrawal of the envelope from the storage compartment.

A further object is the provision of a selfcontained device of this nature which is readily attachable to a calculating machine equipped with printing devices. in place of the carriage with which such machines are provided, and detachable therefrom, to enable tlie carriage to be replaced. The operator can thus list amounts ou envelope or other separate work pieces automatically fed to the printing devices, on the same ma chine which he uses for ordinary Work, b v the mere substitution of the envelop feed mechanism for the carriage. and vice versa.

To these and other ends, .my invention includes certain novel features and combinations of parts, all of which will be more fully set forth hereinafter and particularly referred to in the claims.

I have chosen to illustrate this invention in `connection with the familiar lVales calculating machine, it being understood that my device is not limited in its application thereto, but may be attached to other ,machines as well.

Referring to Fig. 1, the hase 965 of the adding machine supports side frames 967 between which are mounted the keyboard, the accumulating, and the printing sections in sequence from front to rear.

The keys 117 are arranged in denominational orders to correspond with the individual counters 490 and drive members 310 of theaccumulating mechanism, and the individual typecarriers 514 of the printing section.

Amounts are accumulated on the counters as follows:

Depressing keys 117 rocks levers 116 to project stops 11.5 into the paths of the corresponding drive members or racks 310, therebydisplacing the rack detents 221 normally in the paths of the racks.

A series of front arms 312 and rear arms 311 pivotally support the respective racks 310, the front arms being journaled on a cross shaft 300 extending between the side frames 967, and the rcar arms 311 being journaled on a cross rod 301. A restraining and restoring bar 205 connected to a crank 220, normally lies acrossV the paths of the front rack-supporting arms'312 tov prevent the racks from advancing under the influ ence of their drive springs 383, preferably connected to the rear supporting arms 311 7 and the bar 205.

Turning a main drive shaft 200 forwardly, by means of a handlef210", forinstance, rocks an arm 210 fasten the shaft, its free end traversing a cam slot 220a in the crank 220, to swing the crank and withdraw the restraining and restoring bar from in front of the arms 312.

The springs 383 then advance the racks until the latter aren arrested by contact with the projected stops 115, or the rack detente 221 in those denominations wherein no keys have been depressed.

A series of individually rotatable coun-` ters 490 with their respective pinions 435 are independently journaled on an axle 400 normally supported by means, not shown, with the pinions disengaged from the racks.

The main drive shaft, on its forward stroke, advances links 214, one of which is shown connected at one end to the arm 210, and at its other end to a counter-controlling trip rod 303 suspended by hangers 323 from the cross shaft 300. As the main drive shaft and the trip rod approach the ends of their forward strokes, (at whichtimethe racks 310 have reached their advanced positions) the counter-supporting mechanism, not shown, is tripped by the rod 303 to enable the pinions 435 of the respective counters, to mesh with the advanced racks.

The mainl drive shaft on its return stroke, rocks the crank 220 through the arm 210, to cause'the restraining and restoring bar 205 to return the advanced racks. which racks, during their retirement, turn the counters 490 to register thereon the amount set up on the keyboard.

The main drive shaft on its return stroke, also retires the trip rod 303 which, near the end of the return stroke, operates the coun tersuppmting mechanism to disengagethe pin'ions 435 from theracks 310 subsequently' to the retirement of the latter.

Suitable carrying mechanism (not shown) 12o transfers the tens from right to left in the usual manner.

The printing of amounts. set up on the keyboard is accomplished, as follows:

The rear rack-supporting arms 311 carry 12.3 rearward extensions 311 connected by links 515 to the stems of types-carriers 514 in which the types 501 are mounted. The arms 311 as they rock on theferward stroke to advance the racks 310, raise the extensions 311a and the typecarriers 514 to position the proper types at the printing line.

LatchesV 511 journaled on a Cross rod 504, normally lock the spring-driven printing hammers 510 journaled on a cross shaft 500, in cocked positions, the latches being provided with the usual cross over tails 511u to effect cipher printing to the right.

As the extensions 31la rise to position the types, they free suitably supported trip bars 513 to the action of lifting springs 583, to enable the upper ends of the bars to contact and disable the latches 511, in those denominations wherein keys have been depressed.

A universal catch 518 mounted on a shaft 530 restrains the hammers against firing upon the release of the individual latches.

The trip rod 303 tensions the hammer drive springs 580, withdraws the hammerresetting bail 509, and releases the universal catch 518 through the following train of mechanism. Un its forward stroke, the trip rod advances a link 526 connected to one arm of a lever 524 pivoted at 508, to rock the lever. A link 527 connected to the opposite arm of the lever 524 transmits motion therefrom to a lever 525 fast on the cross shaft 500. A link 525a connects this lever with an arm 513l on a shaft 502a which supports a tensioning` bail 505n (shown in dotted lines in Fig. 1) to raise the bail and tension the hammer-driving springs 580 extending betwveen the bail and the respective hammers 510.

Arms 519 on the shaft 500 carry the hammer-resetting bail 509 normallyT in contact with the hammers.

The lever 525 as it turns, rocks the resetting hail out of the paths of the hammers.

releasing link 526 connected to the lever 525. has a slot and pin connection 555 with an arm 517- on the universal catch-supporting shaft 536, and near the end of the forf Ward stroke, after vthe types have been positioned, the link 526 swings the arm 51T 'to displace the universal catch and permit the hammers 510 to drive the types against the paper. A ribbon 890 is interposed between the types and the paper to enable the printing of the amount.

T lie racks 310 on their retirement, return the rear extensions 3112L to retract the typecarriers 514 to normal position and lower trip bars 513 against the tensions of the springs 583, thereby freeing the individual latches 511. Springs (not shown) restore the latches to effective position. The trip rod 303 on its return through the linkage 520, 524, 52T. and 525, forces the hammerrestoring bail 509 against the discharged hammers to cork the latter, relaxes the tension of the hammer-driving springs 580, and frees the universal catch 518 for effective operation.

The machine may be provided With a paper carriage (not shown) including a paper supply, a platen, and line spacing mechanism, which carriage is removably secured to the rear ends of the side frames 967.

A rearwardly extending thrust bar 2026 (lFig. 1) connected at its forward end to a cross bar 302 mounted in the swinging hangers 323, operates the paper feed mechanisln on the carriage.

For a further understanding ofthe vWales machine, attention is directed to U. S. patents to W ales 768,097, August 23, 1904; 594,205, July 11, 1905; and 707,032, August 15, 1905; McFarland and lllales, 880,157, February 25, 1008; and lVales, 940,758, November 23, 1909.

rFhe foregoing mechanism is old and constitutes a part of the present invention only in so far as it is combined with the novel features hereinafter set forth.

.-1 machine of the foregoing type is adapted to accumulate on the counters and record on the paper web or sheet, amounts set up on the keyboard.

Separate work pieces, as cards, envelops. or the like, may be manually inserted around the carriage platen, printed upon, and removed b v hand, but this method is slow and laborious, and l have contrived a novel and simple means interchangeable with the usual paper carriage, which automatically presents the envelops to the printing devic, to receive the imprint, after which the envelops are automatically ejected, all of which is effected through the operation of the niachine in registering amounts on the counters.

l am aware that in the main, this idea broadly is old, but l am not aware that anyone heretofore has provided an envelop feeding device which may be detachably connected to the usual calculating machine in place of the ordinary paper carriage. thereby extending the field of usefulness of the calculating machine with a minimum of expense.

Heretofore, the location of the Writing line on the envelops fed to the printing devices ivas not definitely positioned, there being no means to aline the envelops and locate the Writing line at a predetermined point on each envelop.

ln my invention I have provided means whereby the writing line is located at a predetermined and constant place on each envelop.

In former envelop feeding devices, so far as I am aware, no provision has been made which enables the operator to make and preserve a printed list and a total of the amounts recorded ou the several envelope, at the saine time that the envelops are being printed upon, and from the saine set of devices which print upon the envelope.

I have contrived a combined envelop and paper feeding mechanism, whereby the an'iounts are simultaneously printed by a single set of printing devices on the envelope, and upon a separate paper web, the web being advanced step by step past the printing line as the envelops are successively advanced.

Furthermore, it will also be observed that machines wherein it is only desired to accumulate items arranged in a; single column, can be equipped with my improvement, and thus avoid the necessity for a so-called narrow carriage to print lists on strip paper only.

The operator, with my invention, can list items on the paper web alone, by omitting to supply the device with envelope, and obtain the same result as with an independent lined carriage equipped to feed strip paper, thereby saving the cost of such independent carriage.

Owing to the varying thicknesses 0f the envelop stock, there has been a liability of feeding two or more envelope at a time to the printing devices. This resulted because the ledge or shoulder on the slide employed in many machines to engage beneath the betteln edge of the foremost envelop, to advance the envelop, extended under the edge of the next adjacent envelop as well.

l employ a novel envelop withdrawing or feeding means which can only engage the foranost envelop, and associate therewith means to prevent the withdrawal of the next adjacent envelop due to frictional contact with the envelop being withdrawn.

The paper feeding, and envelop advancing and ejeoting means` and the means tov prevent the frictional withdrawal. of additional envelope, are preferably driven from a single compact mechanism actuated from the thrust bar 20:26 of the calculating machine, incidentally to the operation of regis` tering and printing amounts.

The particular embodiment of my invention herein illustrated, comprises a supportingl fixture 1 (Fig. 1) detachabl)v secured to the side frames 967 by set screws 2 in the same manner as, and in place of. the usual paper carriage. By loosening the screws, the entire self-contained envelop and paper feeding mechanism can be removed and the paper carriage fastened in its place.

Side plates 3 (Figs. 1 and 2) extending rearwardly from the fixture 1 to which they are secured, are connected by brace rods 4, and form a casing for the operative parts of the device. An angular container 5 (Figs. Q and i) located between the side plates 3 and below the plane of the printing devices, cooperates with the side plates to form a storage con'ipartinent for the supply or pack of envelope G introduced thereinto through the open rear end of the casing.

A follow-er 7 in the storage compartment operates to press the envelops upwardly against an arresting plate 8 partially closing theA upper end of the storage compartment.

Ears 9 on the follower plate 7 pivotally engage' a. supporting rod 10 traversing arcu ate slots 11 in the sides 3, the supporting rod being mounted on the rearwardly extending arms of a pairof external levers 12. These levers are fast on a shaft 13 journaled in and extending between the sides 3 of the casing in front of the angular container 5. Springs 14 connected to the remaining arms of the levers press the plate or follower 7 upwardly against the bottoni of the pack of cnVe-lops.

A spring 15 on the supporting rod 10 contactsthe follower plate 7 to cause the automatic adjustment of the latter to the plane of the bottoni of the pack of envelops.

Pressing downwardly upon. aV finger piece 1G extendingv rearwardlyY from the follower plate 7 forces the latter down to enable the insertion of a pack of envelope 6 into the storage compartment. Upon its release, the follower 7 and its supporting levers l2, assume a position substantially like that shown by the dot and dash lines in Fig. :2, the springs 1-1 pressing the follower upwardly.

The envelope in the pack are arranged with their flaps 17 (Fig. Li) uppermost and at the front end of the pack.

Alining guides 18 (Figs. 2, 4 and 11) depend from the rear end of the arresting plate 8 to Contact the rear edgesl of the envelops and maintain them inproper position against sliding rearwardly, the lower free ends of the guides being outwardly curved so that if any of the envelope in: the pack project rearwardly beyond the others, they will be gradually slid forwardlyV by contact with such curved ends as they are pressedV upwardly by the follower 7.

The guides 18A are spaced apart as shown in Fig. 11. to accommodate the finger piece 16 of the follower 7 and thereby enable the latter to pass between the guides and press the bottommost envelop against. the arresting plate 8, in position to be fed tof the printing devices.

The forward end of the arresting plate 8 terminates short of the flaps 17 of the envelops, and is downwardly inclined so that the envelope are slightly squeezed between the follower and the front edge of the arresting plate at a point just clear of the free ends of the flaps, to loosen the flap of the uppermost envelop. and cause it to lift or spring upwardly above the body portion of the envelop.

The envelope are conveyed from the storage compartment through a channel or passage formed between an outer semi-circular confining plate 19 (Figs. 2, 3, 6 and 7) embraced between the upper forward ends of the main side plates 3, and upper and lower guide plates 2U and 21 concentric with the confining plate. The guide plates 20 and 2l are supported at theirI lateral edges by stationary end frames 22 parallel with and inclosed between the side plates 3. A brace rod 4 and a rock shaft 23 extending between the side plates 3 support the end frames 22. The adjacent edges of the guide plates 20 and 21 are spaced apart from each other, the lower guide plate having a rearward extension 2l (Figs. 2 and projecting over the upper end of the storage chamber and being inclined above the plane of the stop plate 8 to enable the flap 17 of the envelop to swing upwardly above the body portion, as shown.

The upper edge of the upper guide plate 20 joins the upper edge of an angular partition 25 (Figs. 2 and a) having a sloping bottom to facilitate the removal of the envelops, which partition is fixed between the side plates 3 above the storage compartment, to form a receiving or collection coinpartnient for the envelops as they are printed.

The lower edge of the outer confining plate 19 joins the upper edge of the angular container 5 (Fig. 7 l and merges at its upper edge into a top plate 2G extending between the side plates 3 to form the cover for the receiving or collection compartment.

A swinging gate 27 having ears 28 pivoted to the side plates 3 at 29, may close the open rear end of the receiving compartment, to retain the printed envelops as they are discharged from in front of the printing devices.

lt will be noted that the passage through which the envelope travel extends from the upper end of the storage, to the upper end of the receiving compartment.

The periphery of a platen 30 mounted on pintles 3,1 journaled in the end frames 22 opposite the printing devices, extends into the passageway between the adjacent edges of the upper and lower guide plates 20 and 21, the outer wall of the passageway or channel formed by the confining plate 19 lying tangentially to the periphery of the platen and being cut away, as shown in F ig. 3, at a point opposite the printing devices to permit the latter' to strike against the platen at the printing line.

The means for positively withdrawing the envclops singly and successively from the storage compartment and advancing them past the printing devices, comprises a pair of injector arms or carriers 32 fixed to the rock shaft 23 and lying parallel with and adjacent the respective outer faces of the supporting plates 22. In the particular form herein selected for illustration, the injector arms terminate in substantially triangular ends, from the rear corners of which project curved injecting fingers or members 33, the forward ends of which traverse the passage between the storage and receiving compartments, along the sides of the upper and lower guide plates 2O and 21 which are narrower than the outside confining plate li) (see Fig.

A coil spring 34 (Figs. 5, 9 and 10) encircles one end of the drive shaft 23 which is journaled in and projects beyond the sido plates 3. One end of the spring is secured to an inclosing housing 35 fastened to the side plate 3, the opposite end of the spring being secured to the drive shaft 23 to turn the latter in one direction. A shrouded gear 36 on the opposite projecting end of the rock shaft meshes with a toothed segment 37 fixed to an intermediate shaft 38 conveniently journaled in the opposite side plates 3 and carrying a crank 39 having a crank pin 40 normally contacted by the rearwardly projected thrust bar 2026, which, through the drive segment 37, normally holds the carrier arms 32 and injector fingers 33, in their advanced positions (Fig. 2), against the tension of the motor spring 34. An anti-friction roll 41 (Fig. may be mounted on the crank pin 40.

On the forward stroke of the main drive shaft 200, the thrust bar is withdrawn relatively to the crank pin 40 to free the rock shaft 23 to the action of the motor spring 34 which thereupon turns the shaft 23 on its forward stroke to swing the injector fingers or members 33 downwardly and rearwardly from their normal advanced positions, shown in Fig. 2, to their retracted or potentially effective positions, shown in Fig. 4, during which movement, the lingers 33 traverse the channel or passageway between the outer confining plate 19 and the iide plates Q0 and 21, and enter the upper orward end of the storage chamber, where they come to rest along the opposite edges of the rearward extension 24 of plate 21, with their free ends projecting below the extension 24 in position to enter between the raised flap 17 and the body of the uppermost envelop. The fingers, as they pass from the channel into the storage compartment, ride over and past the flap 17 of the uppermost envelop of the pack 6, to slightly compress the envelope, and then swing away from the pack to suddenly release the pressure and thereby loosen the flap of the foremost envelop, if it should happen to adhere to the body of the envelop, to enable the Hap to spring upwardly.

The gear 36 on the shaftQE-l rotates the segment 37 to cause the crank pin 40 to follow the thrust bar as the latter is withdrawn.

The main drive shaft 200 on its return, presses the thrust bar 2026 against the crank pin 40, turning the crank to swing the toothed segment 37 in the opposite direction and rotate the shaft 23 on its return stroke, thereby restoring the injector fingers to normal position (Fig. 2). A

The rock shaft on its return stroke, advances the injector fingers 33 to insert them 'y beneath the lifted flap 17 of the uppermost Ii (l envelop, the front ends ol the fingers engaging in the crease at the juncture of the Hap with the body or' the envelop to positively withdraw the envelop from the storage compartment and advance it along the passageway past the printing devices. The extension plate Q-i prevents the Hap from swinging too far upward, which might permit the injector fingers to mutilate the envelop.

To prevent the advancing envelop from drawing with it by friction-al contact, one or more of the adjacent envelops, I provide a restraining mechanism (Figs. 2, 3, 4, and 8) which, in the present instance, comprises a supporting bar 42 extending between and projecting through slots 43 in the side plates il at the upper end of thc angular storage container 5. Arm-s -i-iiXed on a cross shaft 45 journaled in the side plates 3, carry the supporting bar, on which latter are mounted restraining lu s or members i6 etna-'ating in slots 47 (Fig. cut in the upper end of the angular container 5 at its juncture With the coniining plate 19, and extending across the mouth or' the passage leading from the storage compartment. A spring 4:8 (Fig. 8) presses a wiper 4:9 on the shaft 5,aga1nst a cam 50 fixed on `the roc-li shaft 23, which cam normally maintains the restraining lugs 46 in eii'ective position across the passage leading from the storage compartment to pre- 'vent the Withdrawal of the envelops or Work pieces, as shown in Figs. 2 and S. The-mechanisms are so timed that, as the injector members are swung downwardly and rearwardly from their norm-al positions (Figs. 2 and G) to their potentially effective positions (Fig. 4), the cam at first maintains the restraining lugs 46 in effective position, but as the injector members approach the lugs, the high point of the cam 5() retires from the Wiper i9, as shown in dotted lines in Fig. S, to enable the spring 4S to swing the arms -l-i and shift the restraining lugs 46 to inactive position out of the path of the injector members and out oi the charmel, as slioivn in Fig. i.

rThe restraining lugs 4G remain in idle position during the first part of the return stroke of the rock shaft 23 which restores the injector members 33 to normal position lo positively withdraw the envelop from the storage compartment and present it tothe printing devices, until the injector members have passed the lugs, at which time-,the high point of the cam 50 contacts the wiper 49 to force the latter in the opposite direction against the tension of its spring 48 and shift the restraining lugs i6 to effectiveposition across the channel leading from the storage compartment. The positively fed envelop is drawn over the upper ends of the lugs which then prevent additional envelops from being frictionally Withdrawn from the storage compartment.

It will be readily understood that the envelops, after having been advanced by the injector mechanism, might receive the imprint t'rom the printing devices Without further adjustment, but in such event, the positions of the Writing lines on the several envelops might vary, depending upon whether the machine vvas slowly or vigorously stroked, which uneven operation would advance some of the envelops farther than. others.

l prefer to so arrange the mechanism, that the Writing line will be positioned at :t predetermined and constant point on each envelop, and not left to chance or accident, to which end, I provide arresting stops 5l in the channel, against which stops the bottom edges of the envelops Contact, to position the envelops uniformly relatively to the printing line. The arresting stops or bars 51 are pivoted at 52 (Figs. 2 and 8) to the end frames 22, and project through slots 5.5 in the lower guide plate 2l (Fig. (Si) and into registering slots 54 in the outer confining plate 19,-as shown in Figs. 2, i and 7. The forward ends 4of the stops normally lie squarely acrossthe channel, sp1-in 55 (Fig. 2) secured to the opposite ends o the stops, operating to yieldingly maintain them in such effective position. Abutments 5G on the end frames 22 limit the spring-impelled throw of the arresting members 5i., which lie to one side oi' the paths of travel oi the injector Amem-bers 33, and. hence, do not interfere therewith. As the injector members 32E advance the envelop along the channel and in front of the platen 30, the arresting members yield upwardly aga-inst the tension ot spr-ings 55, to permit the passage of the envelop thereunder. The envelop is advanced throughout th-e return stroke of the main drive shaft 200 until the bottom edge of the envelop escapes past the arresting members` which thereupon snap back to active position across the feed channel, as shown in Fio'. 2.

Fortions of the carrier arms 32 extend into thereceiving compartment, when the parts are in normal position shown in Fig. 2, and carry positioning members 5T having abrupt rear faces, pivotally mounted at 5S thereon, in front of the injector lingers 3S.

The positioning members extend across the channel or passageway leading 'from the storage to the receiving compartment, the outer ends of the positioning members traversing slots 59 (@Fgs. Vi3 and 7) formed in the conning plate 19 near the opposite sides of the channel.

Sl i) llO Springs 6() normally maintain the positioning members 57 in effective position across the channel, and lugs 6l limit the spring-pressed throw of the members.

On the forward stroke of the main drive shaft 200, when the motor spring 34 turns the shaft 23 to swing the arms 32 carrying the injector members 33 to their potentially effective position. as shown in Fig. 4:, the injector lingers retire from the [lap 17 to release the envelop which they have just advanced, the points only of the injector fingers traversing the channel. The abrupt faces of the positioning members 57 which follow the injector fingers on this stroke, contact the envelop to feed it baclnvardly until its lower or bottom edge strikes the members 51, which arrest the envelop against further backward travel, so that the imprint of the amount set up ony the keyboard is effected at a predetermined and constant distance from the bottom edge of the envelop, whereby the writingr lines on the respective envelope occupy a uniform position.

After the arrest and alinementof the envelop, the positionin members 57 yield against the tension of wipe idly over the envelop to their positions shown in Fig. 4.

lt will be understood that in using this attachment, the operator before setting up an amount on the keyboard, will first stroke the machine for one idle operation. The forward stroke of the main drive shaft 200, enables the shaft 23 under the influence of the motor spring 34 to retract the injector members 33 to position to engage the uppermost envelop in the storage compartment, and upon the return stroke of the main drive shaft 200, the envelop is presented to the printing devices.

The operator will now set up the amount on the keyboard to be printed on the envelop and then operate the main drive shaft 20() once more, which again retracts the injector mechanism` during which operation the previously fed envelop is brought back by the positioning members 57 to Contact the arresting members 5l. The printing devices operate near the end of the forward stroke, after which it becomes necessary to remove the printed envelop to make room for the succeeding blank envelop, which is advanced to position on the return stroke of the uur i drive shaft. A

The printed envelop might be manually withdrawn. but preferably. l provide means to automatically eject or discharge the printed envelope and deliver them into the receiving or collection compartment. and this I accomplish by utilizing the same mechanism which positions the envelop relatively to the printing devices.

The envelop positioning members 57 on their springs 60 to' the arms 32 readily lend themselves to the function of ejecting the envelops on the return stroke of the drive shaft 23, and to this end, l form hooks or lips G2 (Figs. 2 and 6) on the positioning members to constitute cjecting lingers or members. it being obvious that they might be separate parts instead of integral with the positioning members.

In the normal position of the parts, at the end of the return stroke of shaft 23 (Fig. 2), the ejector members lie within the receiving compartment to insure the complete withdrawal of the discharged envelops from the channel or passageway leading frm the storage cou'ipartnient to the receiving com- 1partn'ient.

On the forward stroke of the shaft 23, the ejector members G2 follow the injector tingers 33 downwardly and rearwardly. The abrupt rear faces of the members 57 which constitute the envelop positioning means, contact the forward edge of the envelop and return it until it strikes the arresting arms 51, whereupon the positioning members yield against the tension of the light springs G0 to permit the members to ride over the edge of and behind the envelop, until they pass the bottom edge of the latter. The springs 60 then restore the members to normal positions with the. hooks 62 facing the bottom edge of the envelop, as shown in Fig. 4, and just in advance of the restraining lugs 46.

On the succeeding return stroke of shaft 23. the ejector members G2. which now lie ahead of the injector fingers 33, advance against the bottom edge of the previously 'ted envelop and drive it along the channel or passageway between the outer confining plate 19 and the upper and lower guide plates 20 and 21, until it is discharged into the receiving compartment.

,lt will be noted that as one envelop is being discharged, the succeeding envelop is being advanced past the printing devices by the injector members 33.

The envelops are ected with considerable force, and strike the closure 27, if the latter is in effective position, upon which the envelope drop one after another to form a fiat pile or stack on the bottom of the receiving compartment.

By raising the rate 27. the envelops, upon their ejection, will be entirely discharged from the machine, passing through the receiving compartment and out of the open rear end thereof, to fall upon a table or other uncolilined area to enable the paymaster to till them in readiness for distribution or to write other data thereon, if desired, thereby effecting an economy in time and labor.

Attention is also directed to the fact that l have utilized rotary means for feeding and ejecting the envelope, rather than the recti- .linearly reciprocating means heretofore emplayed.

Such rotary arrangement enables the device to be embodied in smaller compass, kor condensed and enables me to completely inclose the feed and ejecting members to protect them from injury, and yet provide for unobstructed access to the envelope both before and after feeding them.

To enable the operator to make and preserve a list of the respective amounts printed on the separate envelops or work pieces, simultaneously with the printing of such amounts on the envelops, and with the same set of printing devices, I provide means, operated by the drive mechanism for the envelop injecting and ejecting means, to feed a paper strip or web 63 (Fig. 2) step by step past the idly rotating platen 30.

A roll of paper 64 (Figs. 1 and 2) is journaled on a cross rod 65 removably mounted in the side pieces 3. The forward end of the strip of paper, which may be carbonized on its inner surface, is led upwardly from the roll, behind a guide rod 66 bearing an anti friction roll 67, thence over the convex face of the confining plate 19 in front of the platen 3() and the envelope, as they are fed to the printing devices, and continuing upwardly, the leading edge of the web is inserted between pressure feed rolls 68 and 69 fast on shafts 70 and 71, journaled in the upper forward ends of the side plates 3, in front of a paper cutter 72. The paper lies between the printing devices and the envelops to receive the original imprint which is transferred to the envelops by the carbonized back of the paper web. However, the relative positions of the paper and envelope might be changed without departing from the invention.

One of the feed roll shafts, as 71, (Figs. 1 and 4:) is journaled in slots 73 in the side plates 3, and springs 74 connect the two Shafts 70 and 71 to firmly grip the paper between the rolls.

The paper is fed step by step by means of a cam 75 (Fig. 1) fast on the rock shaft 23, in contact with a follower 76 on the shank '77 of a feed pawl 78 forked at 79 to embrace the drive shaft 23 for guidance, and also supported on a pin'SO passing through a slot S1 in the shank and mounted on the adjacent side plate 3. The feed pawl 7 8 engages a ratchet 82 fixed on one of the pressure roll shafts, Las shaft 70 for instance, and a s ring 83 connected to the feed pawl, normal v retracts the latter.

As shaft 23 turns on its forward stroke, withthe main drive shaft 200, the caen 75 rotates Vin the direction of the arrow (Fig. l) and the spring 83 retracts the feed pawl 78, and causes the follower 76 to ride down to the low point ofthe cam. This enables the feed pawl to pass idly over at least one tooth of the ratchet 82 in readiness to turn the latter. The printing devices operate during this forward stroke, and the paper is stationary while the imprint is being made.

O n the return stroke Aof v.thev shaft 23, the cam 75 forces the follower 7 6 and its feed pawl 78 in the opposite direction, against the tension of spring 83 .to turn the ratchet 82, and pressure rolls `68, 69, to advance the paper 63 preparatory to the next printing operation.

A spring-pressed detent 84 engages the ratchet 82 to prevent reverse rotation thereof.

The paper unwinds freely from the paper supply and to prevent slack in the paper web between the paper roll on one side of the platen and the feed rolls on the opposite side of the platen, I provide a paper brake S5, (Fig. 2) comprisingia plate journaled on a brace rod l and pressed lightly by springs SG against the paper web 63 where it passes over the guide roll G7. Filings 87 on the braking plate embrace the paper supply roll Geil, and the web, to held the former against lateral play and to guide the web.

Obviously, the paper strip alone may be fed past the printing point `to enable the operatorto perform calculations in the ordinary use of the machine, when it is not desired to print envelope, or other work pieces, by omitting to supply the storage compartment, in which case the envelop feeding mechanism will idly operate at each operation of the main drive shaft Q00.

1t will be noted that the injector, ejector and envelop alininlgr devices, the means to prevent the frictional `withdrawal of fenvclops from the storage compartment, and also the paper web feeding mechanism are all driven from the common shaft 23.

Furthermore, the envelop feed and discharge mechanism, and the paper feed mechanism are self-contained and are readily ap plied to and removed from the calculating machine.

Changes may be made in the form and arrangement of the several parts, without departing from the spirit and scope of the in vention.
